Evaluation of centralized wwtp and the need of communal wwtp in supporting community-based sanitation in indonesia

Millennium Development Goals (MDG's) to increase access to clean water require major changes in the water and sanitation sector. MDG's target in 2015 was 50% of the population should be accessible sanitation. Centralized Wastewater Treatment Plant (WWTP) in Jakarta, Bandung and Cirebon were built as an effort to support the city's sanitation. The performance efficiency of WWTP reached 80% and the treated wastewater is accordance with quality standard. But the WWTP in the three cities only serve <20% of the population. Up until now, the greywater from residential, has not optimally treated and into receiving natural water system causing pollution. Domestic wastewater pollution contribution by 60% in the receiving natural water system. Community already aware of the need to treat domestic wastewater as an effort to maintain environmental sanitation. Community expects a communal wastewater treatment. Communal WWTP base community must be built to anwers the sanitation problem in urban area. Positive perception from community could manage of waste water at the communal scale.
